JT’s Strong Arm Jack Stabilizers: Best Overall

Traditional jacks only move up and down, leaving your RV vulnerable to annoying side-to-side and front-to-back sway. JT’s Strong Arm Jack Stabilizers solve this by using rigid steel bars to form a series of solid triangles between your frame and the landing gear. This structural triangulation effectively locks the chassis in place, eliminating almost all lateral and longitudinal movement.

Once installed, these stabilizers remain permanently attached to your rig, making setup at new campsites incredibly simple. You merely lower your jacks as usual, then tighten the heavy-duty T-handles to lock the inner and outer telescoping tubes. The main tradeoff is the initial installation process, which requires some precise bolting or minor welding underneath your chassis.

If you are a full-time fifth-wheel or travel trailer owner who plans to stay in one place for weeks or months, these are the ultimate upgrade. They provide an unmatched level of stability that makes your rig feel like it is built on a concrete slab. If you want the most robust, set-it-and-forget-it stabilization system on the market, JT’s Strong Arms are the right choice for you.

BAL 28012 X-Chock Stabilizer: Best for Sway

Tandem-axle trailers are notorious for front-to-back rocking, which is caused by the natural rotation of the tires even when the brakes are applied. The BAL X-Chock stops this movement at the source by applying opposing force directly between your tandem tires. This locking action prevents the wheels from shifting, creating a highly stable foundation.

Manufactured from heavy-duty steel, the X-Chock features a rust-resistant coating designed to withstand years of outdoor exposure. It operates via a scissor mechanism controlled by a standard ratchet wrench, allowing you to easily adjust the tension. Because it sits off the wet ground between the tires, it will not slip or sink like traditional wedge chocks.

There are a few clear tradeoffs to consider with this wheel-based system. It is designed exclusively for tandem-axle rigs, meaning single-axle trailer owners and motorhome drivers cannot use it. Additionally, you must remember to remove them before moving your rig, as driving with them installed can cause severe tire and axle damage.

If you own a tandem-axle travel trailer or fifth wheel and are tired of the shifting sensation every time someone walks down the hallway, this is a must-have tool. It is highly packable, budget-friendly, and delivers immediate, noticeable results. You should absolutely add a pair of these to your setup if you want to eliminate tire-induced sway.

BAL 24028 Deluxe Scissor Jack: Best Value Upgrade

Factory-installed scissor jacks are often flimsy, prone to rust, and struggle under the heavy loads of full-time living gear. The BAL Deluxe Scissor Jack is a substantial upgrade, featuring a heavy-duty design rated to hold up to 7,500 pounds per jack. Its extra-wide bow-tier frame naturally resists tipping under heavy lateral wind loads.

This jack is coated with a highly durable, rust-inhibiting finish that protects against road grime and salt air. The patented tooth-gear design ensures the jack extends straight up and down without binding or twisting. This smooth operation makes raising and lowering your rig a much smoother, quieter process.

The main drawback is the physical effort required to crank them down manually, though using a drill adapter can speed up the process. They also require permanent mounting, which means crawling under your rig for the initial bolt-on installation. However, the robust construction far outweighs these minor setup inconveniences.

If your current scissor jacks are bent, rusted, or simply feel unstable when your rig is fully loaded, this is your best value upgrade. It offers commercial-grade durability and impressive weight capacity without the high price tag of motorized systems. This is the ideal choice for budget-conscious travel trailer owners seeking reliable ground support.

Camco Eaz-Lift Slide-Out Support: Best for Slides

Slide-outs add valuable square footage to your living space, but they also put immense leverage on your RV’s frame and slide mechanisms. Over time, heavy furniture or constant movement inside the slide can cause the extension rails to sag or wear unevenly. Camco Eaz-Lift Slide-Out Supports place heavy-duty columns directly under the slide frame to transfer this weight to the ground.

Constructed from durable, heavy-duty steel, these supports adjust easily from 19 to 47 inches using a simple pin-lock and screw-thread system. The top of each support features a wide, universal cradle that securely grips the slide-out’s structural beam without scratching the paint. This simple design provides direct, vertical support where your rig needs it most.

There is a critical safety warning to keep in mind when using these supports. If your main RV tires lose air or your primary jacks settle into the ground, the slide-out supports can force the slide upward, causing severe frame damage. Because of this risk, you must check your tire pressure and primary leveling jacks regularly.

This product is perfect for stationary full-timers who leave their massive, heavy slides extended in one campsite for months at a time. If you move frequently or have a smaller rig, the constant setup hassle and risk of frame damage make these unnecessary. But for long-term parking, they offer excellent insurance against expensive slide-out sagging.

Valterra Stabilito Stack Jacks: Best Portability

For space-conscious RVers, bulky stabilization gear can quickly crowd your precious under-bay storage compartments. Valterra Stabilito Stack Jacks solve this problem with their clever, nesting design that allows them to stack inside each other when packed away. Made of cast aluminum, they are exceptionally lightweight yet capable of supporting up to 6,000 pounds each.

Each jack features a simple threaded rod and an integrated T-handle for quick, manual height adjustments. This versatility makes them perfect for targeting specific soft spots under your frame, stabilizing entry steps, or reinforcing bumper-pull tongues. They provide a quick, adaptable way to eliminate localized bounciness throughout your living space.

The tradeoff for this high portability is the manual labor required during setup. You must individually place, adjust, and level each stack jack on every single trip, which can be tedious in bad weather. They also require flat, solid ground or wooden leveling pads beneath them to prevent sinking into soft dirt or gravel.

If you live in a smaller travel trailer, van conversion, or truck camper where storage space is at an absolute premium, these are for you. They offer a highly effective, low-cost stabilizing solution that takes up almost zero space when nested. Skip these if you have a massive fifth-wheel, but buy them immediately if space is your primary constraint.

Lippert Ground Control 3.0: Best Automatic System

If you want to bypass the physical labor of campsite setup entirely, the Lippert Ground Control 3.0 is the gold standard of convenience. This fully automatic electric leveling and stabilization system uses advanced Hall Effect sensors to calculate exactly how to secure your entire rig. With a single touch of a button, your RV levels and stabilizes itself in minutes.

The high-torque electric jacks are bolted directly to your chassis, offering incredible strength and structural rigidity. This system operates much faster than traditional hydraulic setups and eliminates the risk of messy fluid leaks or valve failures. It provides a level of stability that manual jacks simply cannot match, especially on uneven terrain.

The most significant drawbacks are the high cost and the complexity of the initial installation. This is a premium aftermarket upgrade that requires professional wiring, calibration, and structural mounting to your frame. Additionally, if an electrical component fails, you must manually override the system using hand tools, which can be difficult.

If you are a full-time fifth-wheel owner who moves frequently and has the budget, this system is worth every penny. It completely removes the physical strain of setting up camp, allowing you to relax immediately upon arrival. If you value convenience and speed above all else, this is the system you need.

How to Choose the Right Stabilizer for Your Rig

Selecting the perfect stabilization setup depends heavily on your specific RV type, weight, and layout. A massive 40-foot toy hauler requires a vastly different approach than a lightweight 20-foot travel trailer. Your rig’s overall weight and frame length are the primary factors that should dictate your equipment choices.

You must also consider your travel style and how often you change locations. Frequent travelers who move every few days will grow to dislike manual stack jacks or complex bolt-on bars that require tedious adjustments. Conversely, stationary full-timers who stay in one spot for months can invest in highly secure, semi-permanent mechanical solutions.

Finally, analyze your suspension type and any specific weak points, such as bouncy entry steps or heavy slide-outs. Tandem-axle trailers benefit immensely from tire-locking chocks, while motorized coaches often require robust frame jacks to bypass the soft air suspension. Keep these key considerations in mind as you shop:

• Gross Vehicle Weight Rating (GVWR): Match the stabilizer’s capacity to your fully loaded rig weight.
• Ground Clearance: Ensure the retracted jacks will not scrape on steep driveways or highway speed bumps.
• Power Source: Decide between manual hand-cranking, convenient 12V electric power, or heavy-duty hydraulics.

Proper Placement for Maximum RV Rock Reduction

Proper placement of your stabilizers is what separates a bouncy camper floor from a rock-solid living environment. The general rule of thumb is to position your stabilizers as close to the outer corners of the frame as possible. This wide, stable stance maximizes your rig’s footprint and naturally resists tipping forces caused by high winds or movement inside.

However, do not make the mistake of overlooking your suspension’s pivot points. Even with four corner jacks firmly deployed, the leaf springs and rubber tires in the middle of your trailer will still flex and bounce. Placing mid-frame stabilizers or wheel-locking chocks directly between your tandem tires is essential to stop this irritating mid-ship movement.

To get the absolute best performance, always use leveling blocks or plastic pads to reduce jack extension. The further a stabilizer jack extends, the more leverage it loses, making it inherently wobbler and less effective. Keeping your jacks as short as possible by stacking solid blocks underneath will dramatically increase their overall rigidity.

Essential Maintenance Tips for Full-Time Gear

Full-time RV living subjects your stabilization gear to constant exposure to harsh road grime, rain, and coastal air. Without regular maintenance, jack threads will bind, gears will strip, and electric motors will burn out prematurely. Implementing a simple monthly inspection and cleaning routine can easily extend the life of your stabilizers by years.

Cleanliness is your primary defense against premature wear and friction. Periodically spray all threaded rods, pivot points, and gears with a high-quality dry silicone lubricant. Avoid using heavy grease or wet oils, as these act like magnets for road dust, sand, and grit, which will grind down the metal components.

Additionally, take the time to inspect all mounting hardware and weld joints for signs of stress or rust. The intense vibrations of highway driving can slowly loosen mounting bolts over time, creating a serious safety hazard. Tighten any loose fasteners immediately and spray any chipped paint with a rust-inhibiting primer to prevent corrosion.

Why You Should Never Use Stabilizers for Lifting

One of the most common and dangerous mistakes in RVing is using stabilizer jacks to lift your tires off the ground. Stabilizers are designed solely to prevent movement and steady the rig, not to support its massive weight. Attempting to lift your RV with them can bend the jacks, warp your chassis frame, or cause a sudden, catastrophic collapse.

It is crucial to understand the structural difference between leveling jacks and stabilizing jacks. Leveling jacks, typically found on motorhomes, are heavy-duty hydraulic or electric systems engineered to lift thousands of pounds. Stabilizers, such as scissor jacks or stack jacks, feature much thinner metal walls and are only rated to hold a fraction of your rig’s weight.

Always use heavy-duty drive-on ramps or leveling blocks under your tires to level the rig first. Once the coach is level and the tires are bearing the load, gently lower your stabilizers until they make snug contact with the ground or blocks. Your tires and tongue jack must always bear the primary load, while your stabilizers simply anchor the frame in place.

Investing in a high-quality RV stabilization setup is essential for your daily comfort and the long-term health of your mobile home. By choosing the right gear for your specific rig and keeping it properly maintained, you can enjoy a solid, wobble-free living space no matter where the road takes you.

Frequently Asked Questions (FAQs)

What does an RV stabilizer do on a travel trailer or camper?

An RV stabilizer reduces side-to-side and up-and-down movement caused by people walking inside the camper or wind hitting the exterior. Unlike leveling jacks, stabilizers are not engineered to lift the weight of the vehicle. Instead, they press firmly against the ground or lock tandem wheels to damp suspension bounce. For maximum effect, full-timers pair frame-mounted scissor stabilizers with wheel chocks to lock both the chassis and axles.

What is an RV king pin stabilizer tripod used for on fifth wheels?

King pin stabilizer tripods support the forward overhang of a fifth-wheel trailer to eliminate front-bedroom sway and vibration. The steel tripod attaches directly to the king pin hitch box, distributing horizontal movement down through three wide-stance legs. This setup stops the flexing motion that occurs when walking in upper-deck fifth-wheel floor plans. Full-time campers typically adjust the threaded screw or chain tensioner until the tripod holds 50 to 100 pounds of upward pressure.

How do you stop an RV from rocking when living in it full-time?

Stopping RV motion requires combining frame stabilizers, between-tire locking chocks, and cross-bracing support arms beneath the chassis. Start by leveling the trailer with leveling blocks under the tires before lowering your corner jacks. Next, tighten between-wheel locking stabilizers like X-Chocks to keep the suspension from shifting front to back. Finally, attach triangulated stabilizer bars such as JT’s Strong Arms between the frame and jacks to stop lateral sway completely.

How do you level and stabilize an RV on uneven campsite ground?

Leveling an RV on uneven terrain begins by parking the low tires on curved leveling ramps before lowering any stabilizer components. Check your bubble or digital level, apply the parking brake, and disconnect the tow vehicle. Place heavy-duty jack pads under the corner stabilizers to distribute weight across soft dirt or gravel. Lower each stabilizer jack until it makes firm contact with the ground pads, adding about one extra turn of pressure without lifting the tires.

Are X-Chock wheel stabilizers better than standard plastic wedge chocks?

X-Chock wheel stabilizers provide significantly more stability than wedge chocks because they expand between tandem tires to lock both wheels in place. Standard wedge chocks sit on the ground and only prevent the trailer from rolling away down a slope. In contrast, X-Chocks apply opposing force directly against both tire treads, eliminating wheel rotation caused by internal foot traffic. Full-timers achieve the best results by using wedge chocks for safety during hitching, then installing X-Chocks once unhitched.

How much do RV stabilizers cost for full-time rigs?

RV stabilizers generally cost between $60 and $800, depending on whether you purchase basic manual jacks or comprehensive multi-point stabilization systems. A pair of manual scissor jacks costs $60 to $120, while between-tire locking chocks run $80 to $150 per pair. Heavy-duty cross-brace stabilizer kits, such as MORryde or Lippert lock arms, range from $250 to $500 for hardware. DIY installation requires only basic wrenches and a drill, whereas professional shop labor adds roughly $100 to $200 per hour.

Why does my RV still shake with stabilizer jacks extended?

Excessive RV shaking usually occurs when stabilizer jacks are overextended or when axle leaf springs and rubber tires flex under movement. Scissor jacks lose lateral rigidity the farther their arms stretch toward the ground. To fix this, place wood blocks or modular jack pads under each foot pad to keep the jack arms shorter and sturdier. Adding wheel-locking chocks between tandem axles stops the tire bounce that corner jacks cannot control.

Is it safe to lift an RV off the ground with stabilizer jacks?

Lifting an RV with stabilizer jacks is extremely dangerous because stabilizers cannot support thousands of pounds of vehicle weight. Raising tires off the ground with scissor jacks can bend the jack screw threads, buckle the chassis, or cause the trailer to slip and fall. Stabilizer jacks are built solely to steady the rig against movement, not to lift it for tire changes or leveling. Always lift the trailer using the tongue jack or hydraulic leveling jacks rated for gross vehicle weight.
